Thanks for the reply!
Specifically, my intent is to have a webpage accessable over a network that can interact with various people but I need it to have two way interaction.
I have figured out how to get the contents of variables displayed on the webpage dynamically (currently stored information from arduino to webpage) but I can't figure out the easiest way to go the other way (information changes back to the arduino to do something like call a function manually or set the state of a boolean etc).
Lost of examples on how to set the state of a pin remotely, but nothing about internal variables.
I'm new at this and my head is beginning to hurt
